> Maybe that's what Jesus used on the people that he healed

I think this is what all healers used. They were all way ahead of their time and clearly misunderstood.

In the whole Christian tradition, God/Jesus generally does not go for organ or limb regeneration. Two counter examples are a healed ear in Luke (but this may well have been resumption of hearing? details are a little light), and then a single Spanish example in the 1600s.

For His own mysterious reasons, He simply doesn’t go in for that stuff, however much intercessionary prayer ends up in His inbox.

Jesus, if he existed, didn't actually heal anyone or perform any miracles. That's mythology, not reality.
